Verifying Your Google Fit 'Physical Activity' Permissions
The Challenge app must have 'Physical Activity' permissions to access your Google Fit step data. There are two ways to verify if those permissions have been granted:
1) Click on your settings for Android phone and select "Apps" (Image #1); -> then select "Permissions" (Image #2) -> then select "Physical Activity" (Image #3) -> then scroll to see if your Challenge app has been granted permission to access your physical activity data from Google Fit (Image #4). If the Challenge app is listed under 'Denied' (vs. 'Allowed'), click it and select "Allow physical activity for this app". If the Challenge app is not included in either the 'Allowed' or 'Denied' list, please unpair and repair Google Fit in the Challenge App.
2) On the main page of the Google Fit app (Image #5), click the 'browse icon' on the button menu -> then click the 'Activity' button on the health data page (Image #6) -> then click the menu button on the top right corner and select "Connected apps" (Image #7) -> then click on the Challenge apps to verify that the app has access to the physical activity data in your Google Fit account (Image #8). If the Challenge app is not included in the list, please unpair and repair Google Fit in the Challenge App.
